Blockchain pilots
Culture Token – Project outline, last update: 23 August 2019Why Blockchain pilots ?
The City of Vienna wants to…
• Learn by implementing
• Use possibilities and chances offered by the Blockchain technology
• Find use cases to optimize processes
• Figure out the role of the administration
• Use token economy in a useful way
• Clarify legal questions
• Live open innovation:
Innovation through openness & cooperation with economy and science
• Link to the Blockchain community in Vienna1st Blockchain-Pilot of the City of Vienna: OGD history and notarization • Secure the integrity of OGD (Open Government Data) by unique document identifiers (hash values) in public Blockchains • Keep track of document-changes • https://digitales.wien.gv.at/site/op en-data/blockchain-pruefen/ • Go live: 14.12.2017
The Blockchain enables reproducible public proof
without central authority
1 Document is created and published online
2 Unique document identifier (SHA256 hash)
is inserted in Public Blockchain
3 Record is timestamped through Blockchain Network
